I was 25 and in the middle of my second year of law school when I started feeling tired, thirsty, and hungry. I had blurry vision all the time. I was lucky — I mentioned this to a friend, and she said whenever she complained about her eyes her dad tested her blood sugar, because that's how he got diagnosed with diabetes. I had a family history of both types, but I figured I was too old for Type 1 and too young and too much of a gym rat for Type 2. Still, I went to student health.
